Zinc-air battery set to challenge dominance of lithium-ion

Move over, lithium-ion. A start-up company in northwestern Montana reports that it has solved the rechargeable problem that has dogged zinc-air battery development and will soon be in competition with the dominant lithium-ion technology.

Ron Brost, CTO and CEO of ZAF Energy Systems, reports his research team has developed a zinc-air prototype that produces two times the energy of a lithium-ion battery at a third of the cost, with applications ranging from powering cell phones to airplanes.

The technology, which has four (or pending) patents, was developed by an offshoot of four-year-old ViZn Energy Systems (formerly Zinc Air, Incorporated), which is beginning to commercialize its zinc-iron redox grid batteries.
